Bartek from the Deno team here. Thanks for the feedback. I assure you this is not a short-sighted change. This has been a problem since before Deno 1.0. We resorted to hacks like different set of globals for user code and different for code inside node_modules/ directory. It was a maintenance headache, made global lookups super slow and was really hard to explain to users. While Web "setTimeout" might have been nice in the beginning the fact that it required additional APIs like "Deno.unrefTimer" made it worse than Node's setTimeout.
